At the Jazz Band Ball Hackett 1938
In a program called "Saturday Night Swing Club" here is a performance of Bobby Hacket's Jazz Band in 1938.
Next to Hackett on cornet are Pee Wee Russell on clarinet and George Brunies on trombone.
I found Brunies' behavior quite annoying. He plays the showman, the one who's trying to save the show and to make it funny
